A VC: The PeopleWeb Another post on the idea of sell-side advertising where: The idea is if you've got an ad, you just put it out on the net somewhere, tag it, and let the ad networks' crawlers come get and run it wherever. I do think that this is a next logical extension of AdSense, where companies who advertise on there would post there ads, and pay for desired results. I would think the first to adopt this would be those who have a clear transactional result, as that would be easiest to track.
